Proper Helmet Adjustment and Fit

CAUTION:
  • Always read and follow the owners manual provided by your helmet supplier.
  • Follow the sizing guide provided by the manufacturer to ensure correct helmet size.
  • This guide covers the use of helmets with common fitting mechanisms. But many helmets have different fit mechanisms that those described in this guide.
  • When riding, childrens' helmets should periodically be re-checked for tightness and positioning. Pay particular attention to any forward or backward shift of the helmet (see Step 2 below).

Step 5

Adjust the chin strap so that it is snug (but not too tight) against the riders chin.  As a guideline (1) the strap should push against the riders chin when the rider's mouth is fully open and (2) you should be able to just barely fit three fingers between the chin strap and the rider's chin.
